These are off the rear of my K5 - they've served as bumpstops for years and have made some contact with the frame rails. I'd say that out of the original 14" of travel, they now have 6-9" each. Still are charged, still function, just in a curve rather than straight line.

Was going to pitch them, but they've served me so well I figured someone could use em.

They are valved as singles, not that it matters much at this point, and have the universal eyelets at both ends.
